Noel, VK3AL, describes their antenna setup and asks for Dave’s opinion. Between a steel fence, close houses, and other antennas, is it possible for Noel to setup another antenna?

I Ran Identical Benchmarks on Windows and Linux… Here’s What Happened
I ran identical benchmarks on the same PC using Windows 11 and Linux Mint to see if switching operating systems actually affects performance.
No tweaks. No hardware changes. Just a clean install, real tests, and surprising results.
If you’ve ever wondered whether Linux can match or outperform Windows on modern hardware—or if your PC is leaving performance on the table—this answers it.

Tower Upgrade Part 2 - Extending the Antenna Mast To Full Height
After getting the first section up in Part 1, I go back over everything, tighten it all down, fix a few small issues, and then push on to extend the mast to its full height with the Yagi on top.
This part includes:
– dropping the tower again to make final adjustments
– trimming the top section and correcting clearances
– adding the third pole and refining the guying geometry
– routing coax through the mast
f- itting connectors and sorting out a few “field engineering” surprises
a- nd working through the reality that every single part of this system is a single point of failure
There’s a moment where you realise the scale of what you’ve built – and also that there’s no going back once it starts going up.
On the Sunday, we clear back trees to give the antenna space it deserves… and then comes the first proper full lift to around 19 metres with the Yagi on top.
I’ve left that section to breathe a bit, with some rather atmospheric music – because honestly, watching something like this go up feels a bit special.
Final tweaks include:
– correcting the magnetic sensor orientation
– tightening clamshells and hardware
– checking the new rotator behaviour
– and noting the shift in resonance now the antenna is at height
The result?
Around 2.5–3 dB improvement from the extra height alone — which in radio terms is a very real step forward.
There’s still more to do, but the tower is now properly up and working.
We’ll do some on-air testing and live streams next to see how it performs in the real world.
Thanks for watching.

Check Out This Awesome Mobile HF Setup! POTA 'Yota
On Saturday I ran into some fellow hams at the park doing a group POTA activation. One of them, David, N0LUV, had a really awesome setup in his Toyota Tacoma and gave me a tour. He’s got more cool stuff packed into this truck and he’s not even done yet! I thought this was so cool and wanted to share it with you.

@jinks6410 wants to create a multi-band center-fed dipole for portable use. He wants to create attachments he can add to the main antenna to cover 10, 12, and 15 meters. Does such an antenna already exist?
